A nurse is reviewing the laboratory results of a client who has atrial fibrillation and a prescription for warfarin. After informing the provider that the INR is 2.5, the nurse should expect which of the following prescriptions?

Decrease the dose of the medication.

Increase the dose of the medication.

Withhold the medication.

Administer the current dose of the medication.

Answer and Explanation

The Correct Answer is D

Choice A Reason:
Decrease the dose of the medication is incorrect. Lowering the dose could potentially drop the INR below the therapeutic range, increasing the risk of clot formation.
Choice B Reason:
Increase the dose of the medication is incorrect. Raising the dose might push the INR above the therapeutic range, increasing the risk of bleeding.
Choice C Reason:
Withhold the medication is incorrect. Withholding the medication might lead to inadequate anticoagulation and an increased risk of clot formation.
Choice D Reason:
Administer the current dose of the medication. An INR of 2.5 is within the therapeutic range for many indications, including atrial fibrillation. This means the blood is appropriately anticoagulated to prevent clot formation without an excessive risk of bleeding. In this scenario, maintaining the current dose of warfarin is often appropriate to sustain the desired therapeutic effect.

Correct Answer is C

Explanation

Choice A Reason:
Increase in serum glucose is incorrect. Desmopressin, which is a synthetic form of vasopressin, primarily affects water reabsorption in the kidneys and doesn't directly impact glucose levels. Therefore, an increase in serum glucose wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.
Choice B Reason:
Decrease in blood pressure is incorrect. Desmopressin is primarily used for its antidiuretic effect, concentrating urine by increasing water reabsorption in the kidneys. It typically doesn't have a significant impact on blood pressure. Therefore, a decrease in blood pressure wouldn't typically be an anticipated therapeutic response to desmopressin in this context.
Choice C Reason:
Decrease in urine output is correct. Desmopressin is a synthetic form of vasopressin (antidiuretic hormone) used to treat diabetes insipidus, a condition characterized by excessive urination and extreme thirst due to the inability to concentrate urine. The primary goal of desmopressin is to reduce urine output by increasing water reabsorption in the kidneys, thereby decreasing excessive urination. Therefore, a decrease in urine output would indicate a therapeutic response to the medication in this context.
Choice D Reason:
Increase in WBC count is incorrect. Desmopressin's action is centered on affecting kidney function by regulating water reabsorption and does not involve changes in white blood cell count. Consequently, an increase in WBC count wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.

A. Apply the patch to a hairless area of the skin. B. Apply a 4x4 dressing over the patch. C. Apply the patch to the same site every 24 hr. D. Apply the patch to a bony prominence on the chest.

Correct Answer is A

Explanation

Choice A Reason:
Apply the patch to a hairless area of the skin is correct. Nitroglycerin patches should be applied to a clean, hairless area of the skin to ensure proper absorption of the medication. Hair can interfere with the patch's adherence and the absorption of nitroglycerin into the bloodstream. The site chosen should be rotated to prevent skin irritation or tolerance development. Commonly used areas include the chest, upper arms, or torso, but it's important to follow specific instructions provided by the healthcare provider.
Choice B Reason:
Apply a 4x4 dressing over the patch is incorrect. Covering the nitroglycerin patch with a dressing may interfere with its absorption and effectiveness. These patches are designed to be applied directly to the skin without covering.
Choice C Reason:
Apply the patch to the same site every 24 hr is incorrect. Repeatedly applying the patch to the same site increases the risk of skin irritation or tolerance to the medication. It's crucial to rotate patch sites to avoid these issues.
Choice D Reason:
Apply the patch to a bony prominence on the chest is incorrect. Nitroglycerin patches should not be placed on bony prominences because these areas can be uncomfortable and may not provide optimal absorption. Instead, they are typically applied to relatively flat, hairless areas of the skin.
